Title: Lead frame for semiconductor
Inventor: WATAKARI SATOSHI
IPC: H01L23/50
Filed: 1990-10-03
Abstract: PURPOSE:To obtain a lead frame where a wire is prevented from coming into contact with an island or an island support lead by a method wherein the corners of the island are rounded or chamfered, and the island support lead is set small in width. CONSTITUTION:An island 1 is set large enough in size so as to allow the mounting deviation of a semiconductor chip 3 and the squeeze-out 7 of adhesive agent. The radius of a circle in contact with the corner of the semiconductor chip 3 or the rounding radius R of the corner of the island 1 is represented by a formula. After the corner of the island 1 is determined in shape, an island support lead 2 is jointed to the corner of the island 1. At this point, the island support lead 2 is, at least, so formed as to be equal in thickness and width taking its strength and processability into consideration so as not to enable a wire 6 which connects a pad 4 with a lead 5 to traverse the island support lead 2. If the corners of the island 1 with which the chip 3 comes into contact are chamfered, the same effect as above can be obtained.

Title: Semiconductor device having multilayer interconnection structure
Inventor: ISOBE AKIRA
IPC: H01L21/768
Filed: 1987-10-21
Abstract: PURPOSE:To prevent the film thickness of an interlayer insulating film in a through hole aperture part from locally and largely fluctuating, and prevent the generation of failure in contacts to connect the upper and the lower wiring layers, by forming step-difference unevenness or of a dummy pattern at the through hole aperture position when a wiring layer under said position is formed. CONSTITUTION:After Al is spread by sputtering or the like, on an insulating film 2 arranged on a semiconductor substrate 1, Al wiring layers 3 of a first group and a dummy pattern 4 are subjected to patterning and formed. Polyimide is spread on the whole surface, and a first interlayer insulating film 5 is formed. After a through hole is made in the first insulating film 5, Al wiring layers 6, 6a of a second group are formed. Then polyimide is spread on the whole surface and a second interlayer film 7 is formed. Through holes 7a, 7b are made at positions where the Al wiring layer 6, 6a are arranged on the second interlayer insulating film 7. The wiring layer 8 of a third group is successively formed, so as to fill up the through holes 7a, 7b. By arranging the dummy pattern 4 between the Al wiring layers 3, the surface of the insulating film 7 is effectively flattened.

Title: Semiconductor integrated circuit
Inventor: TAKESHITA KOICHI
IPC: H03K17/16
Filed: 1991-10-15
Abstract: PURPOSE:To prevent malfunction due to noise between a power supply and a GND by providing a signal to control an output in the integrated circuit and using its output control signal so as to give an input. CONSTITUTION:Inverting logic INV 3, 4, a transfer N-channel MOSFETM5 and a transfer P-channel MOSFET6 form an output circuit. Then a delay time of a delay circuit DELAY is decided by assuming a time duration when noise takes place between a power supply VDD and a GND synchronously with a rise of an output control signal C1 and a fall of an input control signal C2. A timing when noise is generated between the power supply VDD and the GND takes place when the control signal C1 changes from L to H. Suppose that the width of noise caused at that time is e.g. 20ns, the delay time of the DELAY 1 is set to nearly 20ns. Thus, the input circuit is separated from the power supply GND by a width of an L level of the control signal C2 and the preceding state is kept without receiving the effect of noise.

Filed: 1993-10-25
Abstract: PURPOSE: To provide a method and a device capable of inspecting a monitoring circuit in relation to vehicle engine control. CONSTITUTION: A monitoring unit 12 for monitoring a computer 10 controlling an engine produces a reset pulse 16 to reset the computer to monitor the computer if there is no check pulse 14 from the computer. If the stop of the engine is detected from the shutoff of an ignition switch 26, power is fed to the computer even after the engine stop, and then the monitoring unit is inspected. In this case no check pulse is output to the monitoring unit. When the monitoring unit produces no reset pulse because no check pulse is produced, the monitoring unit is determined to be in failure.
